Microsoft is working with major PC manufacturers and retail partners to make it simpler than ever to try and buy Office 2010. Through retail partners, Microsoft’s introducing “Product Key Card” to help consumers more easily access and experience Office 2010 on new PCs that’ve been pre-loaded with Office 2010. The Product Key Card is a single license card (with no DVD media) that’ll be sold at major electronic retail outlets. The key number contained on the card’ll unlock Office 2010 software that has been pre-loaded by the PC manufacturers on their PCs, and enables a simpler and faster path for consumers to begin using any one of three full versions of Microsoft Office – Office Home & Student 2010, Office Home & Business 2010, or Office Professional 2010.
Also unveiling “Click-to-Run,” that makes it easier for customers to try or buy Office digitally by significantly reducing the time and effort required to download Office 2010 over Internet. Click-to-Run automatically downloads and installs any software patches when connected to Internet, helping people maintain and keep their Office software up-to-date.
